5、列出所有版本信息

lsb_release -a

[root@ihdemj0ovr /]# lsb_release -a

Distributor ID: CentOS

Description: CentOS Linux release 7.6.1810 (Core)

Release: 7.6.1810

Codename: Core

[root@ihdemj0ovr /]# lsb_release -a

-bash: lsb_release: command not found

出现command not found说明没安装lsb_realease，可以执行命令yum install -y redhat-lsb安装lsb_realease，安装完成后，版本信息如下：

[root@ihdemj0ovr /]# lsb_release -a
